Table 1. Genetic variation of SSR marker loci (heterozygosity) and virulence factors (Nei’s diversity) and Hardy-Weinberg equilibrium (HWE) tests for non-random association (p value in parenthesis) in the seven P. infestans populations each composed of 20 genetically distinct isolates sampled from China.
